C&K 7101SD9CME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SD9CME is a toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This through-hole mounted switch features a standard round actuator with epoxy sealed terminals and is designed for On-On switching applications. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the 7101SD9CME is determined by the following critical parameters:

Direct Equivalent Category: Parts maintaining identical electrical ratings (5A at 120V AC / 28V DC), SPDT circuit configuration, On-On function, through-hole mounting, PC pin termination, and operating temperature range (-30°C to 85°C).

Similar Substitute Category: Parts sharing SPDT circuit configuration, On-On function, through-hole mounting, PC pin termination, and operating temperature range, but with reduced electrical ratings (0.4VA at 20V AC/DC) and lower electrical life (40,000 cycles). These parts are suitable for applications where the full 5A/120V rating is not required.

The 7101SD9CSE (C&K) qualifies as a direct equivalent with active product status. The E-Switch 100 series parts (100SP1T1B2M2QE, 100SP1T1B4M2RE, 100SP1T3B4M2RE) and Grayhill 34ASP13B4M2RT qualify as similar substitutes with reduced electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: The C&K 7101SD9CSE is the primary substitute for the obsolete 7101SD9CME. Both parts maintain identical electrical specifications (5A at 120V AC / 28V DC), circuit configuration, and mechanical form factor. The 7101SD9CSE has active product status, ensuring long-term availability. Note that the 7101SD9CSE carries REACH Affected status compared to REACH Unaffected for the original part.

Similar Substitute Selection: The E-Switch 100SP1T1B2M2QE provides a substitute option when the full 5A/120V rating is not required, maintaining the same electrical life rating of 40,000 cycles. The E-Switch 100SP1T1B4M2RE and 100SP1T3B4M2RE, along with the Grayhill 34ASP13B4M2RT, are suitable for low-power applications with reduced voltage and current requirements (0.4VA at 20V). All similar substitutes are ROHS3 compliant and REACH Unaffected.

Actuator Length Consideration: The 7101SD9CSE maintains the original 12.45mm actuator length. E-Switch alternatives offer 10.41mm (100SP1T1B2M2QE, 100SP1T1B4M2RE) or 13.97mm (100SP1T3B4M2RE) lengths. Grayhill 34ASP13B4M2RT provides 13.97mm actuator length. Panel cutout compatibility must be verified for applications with tight mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the 7101SD9CSE directly replace the 7101SD9CME? A: Yes. The 7101SD9CSE is a direct equivalent with identical electrical ratings (5A at 120V AC / 28V DC), SPDT configuration, On-On function, through-hole mounting, and PC pin termination. Both parts operate across -30°C to 85°C. The primary difference is product status: 7101SD9CSE is active while 7101SD9CME is obsolete.

Q: What is the difference between direct equivalents and similar substitutes? A: Direct equivalents maintain all electrical and mechanical specifications of the original part. Similar substitutes share the same circuit configuration and mounting type but have reduced electrical ratings. The E-Switch 100 series and Grayhill 34ASP13B4M2RT are rated for 0.4VA at 20V instead of 5A at 120V, making them suitable only for low-power applications.

Q: Are there actuator length differences between substitutes? A: Yes. The 7101SD9CSE maintains the original 12.45mm length. E-Switch 100SP1T1B2M2QE and 100SP1T1B4M2RE offer 10.41mm actuators, while 100SP1T3B4M2RE and Grayhill 34ASP13B4M2RT provide 13.97mm actuators. Panel cutout dimensions must be verified for mechanical compatibility.

Q: Are all substitutes RoHS and REACH compliant? A: All listed substitutes are ROHS3 compliant. For REACH status: 7101SD9CSE is REACH Affected; E-Switch 100 series and Grayhill 34ASP13B4M2RT are REACH Unaffected. The original 7101SD9CME is REACH Unaffected.

Q: What is the electrical life difference between parts? A: The 7101SD9CME and 7101SD9CSE are rated for 100,000 cycles. All similar substitutes (E-Switch 100 series and Grayhill 34ASP13B4M2RT) are rated for 40,000 cycles. Application duty cycle requirements must be considered when selecting lower-rated alternatives.

Q: Can I use a similar substitute in a 5A/120V application? A: No. Similar substitutes are rated for 0.4VA at 20V maximum and are not suitable for applications requiring 5A at 120V. Use only the 7101SD9CSE for full electrical specification compatibility.
